Subject: [PATCH] Increase nodemap hash.
X-Git-Tag: v2.6.14-rc1~44
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f297e4e5e4245a5c3fb36e7f754cde96cdb4bc43;p=linux-2.6

[PATCH] Increase nodemap hash.

Needed for some newer Opteron systems with E stepping and memory
relocation enabled. The node addresses are different in lower
bits now so the nodemap hash function needs to be enlarged.
